Genetic structure and diversity of Senefeldera verticillata (Euphorbiaceae) in semideciduous seasonal forest fragments
Authors: A.A.R. Vieira, A.L. Silva J?ºnior, L.C. Souza, F.D. Miranda, M.F.S. Ferreira and M.V.W. Caldeira
Senefeldera verticillata (Euphorbiaceae) is a species that exclusively occurs in the Atlantic Forest; it is used in the restoration and recovery of degraded areas and has therapeutic uses. Due to the scarcity of information on genetic patterns of this species, genetic diversity was characterized by the use of molecular markers.. Read More»

Contemporary pollen and seed dispersal in natural populations of Bertholletia excelsa (Bonpl.)
Authors: A.B. Baldoni, L.H.O. Wadt, T. Campos, V.S. Silva, V.C.R. Azevedo, L.R. Mata, A.A. Botin, N.O. Mendes, F.D. Tardin, H. Tonini, E.S.S. Hoogerheide and A.M. Sebbenn
Due to the nutritional content and commercial value of its seeds, Bertholletia excelsa is one of the most important species exploited in the Amazon region. The species is hermaphroditic, insect pollinated, and its seeds are dispersed by barochory and animals. Because the fruit set is dependent on natural pollinator activity, g.. Read More»

Population genetic structure of three species in the genus Astrocaryum G. Mey. (Arecaceae)
Authors: N.P. Oliveira, M.S.P. Oliveira, L.C. Davide and S. Kalisz
We assessed the level and distribution of genetic diversity in three species of the economically important palm genus Astrocaryum located in Pará State, in northern Brazil. Samples were collected in three municipalities for Astrocaryum aculeatum: Belterra, Santarém, and Terra Santa; and in two municipalities for .. Read More»

Genetic diversity analyses of tropical goats from some countries of Middle East
Authors: R.M. Al-Atiyat
The genetic structure of 10 goat breeds from four countries of the Middle East and Horn of Africa was investigated at 17 microsatellite loci. The average allele number and richness were 9.65 and 5.78, respectively. The mean expected heterozygosity per population was 0.703, 0.715, 0.719, 0.699, 0.749, 0.719, 0.731, 0.721, 0.719.. Read More»

Restoration over time and sustainability of Schinus terebinthifolius Raddi
Authors: S.V. ?lvares-Carvalho, R. Silva-Mann, I.B. Gois, M.F.V. Melo, A.S. Oliveira, R.A. Ferreira and L.J. Gomes
The success of recovery programs on degraded areas is dependent on the genetic material to be used, which should present heterozygosity and genetic diversity in native and recovered populations. This study was carried out to evaluate the model efficiency to enable the recovery of a degraded area of the Lower São Francis.. Read More»

Genetic structure in fragmented populations of Solanum lycocarpum A. St.-Hil. with distinct anthropogenic histories in a Cerrado region of Brazil
Authors: T.M. Moura, K. Martins, P.S. Sujii, A.M. Sebbenn and L.J. Chaves
Solanum lycocarpum is a woody tree widely distributed in the Cerrado that reaches high population densities in disturbed environments. We examined the genetic diversity and population differentiation of six S. lycocarpum populations with different degrees of human disturbance in order to determine if they are negatively affected by anthropogenic activity...

Comparative analyses of genetic/epigenetic diversities and structures in a wild barley species (Hordeum brevisubulatum) using MSAP, SSAP and AFLP
Authors: X.H. Shan Y.D. Li X.M. Liu Y. Wu M.Z. Zhang W.L. Guo B. Liu Y.P. Yuan
We analyzed genetic diversity and population genetic structure of four artificial populations of wild barley (Hordeum brevisubulatum); 96 plants collected from the Songnen Prairie in northeastern China were analyzed using amplified fragment length polymorphism (AFLP), specific-sequence amplified polymorphism (SSAP) and methylation-sensitive amplified polymor..

Pedigree analyses in the Breeding Program for Nellore Cattle
Authors: Vozzi PA, Marcondes CR, Bezerra LAF and Lobo RB
Parameters based on the probability of gene origin were used to describe genetic variability in three reproductive groups from the Breeding Program for Nellore Cattle (PMGRN). The three reproductive populations (cows in reproductive age, bulls from artificial insemination centers and young bulls in progeny test) generated medi.. Read More»

Cross-amplification and characterization of microsatellite loci in Acropora austera from the south-western Indian Ocean
Authors: P.H. Montoya-Maya, A.H.H. Macdonald and M.H. Schleyer
Here, we report the successful cross-species amplification of previously published acroporid microsatellite markers in the coral Acropora austera from the south-western Indian Ocean. This fast-growing species is a major reef-building coral on South African reefs; however, it is the most damaged coral by scuba diving activity, .. Read More»

Gene flow from transgenic to nontransgenic soybean plants in the Cerrado region of Brazil
Authors: Abud S, de Souza PIM, Vianna GR, Leonardecz E, Moreira CT, Faleiro FG, Junior JN, Monteiro PMFO, Rech EL and Aragao FJL
Evaluation of transgenic crops under field conditions is a fundamental step for the production of genetically engineered varieties. In order to determine if there is pollen dispersal from transgenic to nontransgenic soybean plants, a field release experiment was conducted in the Cerrado region of Brazil. Nontransgenic plants w..
